The solution to the system of equation are x = -2 and y = 3
<h3>How to find the solution of a system of equation?</h3>
x + 3y = 7
2x + 4y = 8
Let's isolate x in the first equation
x = 7 - 3y
substitute the value of x in the second equation.
Therefore,
2(7 - 3y) + 4y = 8
14 - 6y + 4y = 8
-2y = 8 - 14
-2y = -6
y = -6 / -2
y = 3
Hence,
x + 3(3) = 7
x = 7 - 9
x = -2

Answer:
b = 1/4m
Step-by-step explanation:
A baker uses 4 berries for every muffin which equation can be used to find the number of berries b needed to make m muffins
Given :
Berries = b
Muffins = m
4 berries for every muffin
4b = m - - - (1)
Th number of berries to make m muffins:
Make b the subject :
Divide both sides by 4
b = m/4
Answer:
y = 0.5, 1, 1.5, 2
Step-by-step explanation:
x is twice as much as y, so when you multiply the input for y by 2, it should get the value of x. Example: if y is 1, then x is 2, because 1*2 = 2

Let's the name the first number x and the consecutive number x + 1. The sum of both of these numbers equals to 53.
We now have our equation:
x + x + 1 = 53
Now solve for x.
x + x + 1 = 53
2x + 1 = 53 <-- Combine like terms
2x = 52 <-- Subtract 1 from each side
x = 26
So, the first number is 26 and the second number is 27.
Answer:
The shoes at the other store could be at the most 70.13.
Step-by-step explanation:
In order to find this, we need to set them equal to each other. Start by multiplying the first cost by the amount of the total price you'll be paying.
65.75 * 80%
And the other side would be the amount of the total price being paid times x.
x * 75%
Now set them equal to each other and solve.
65.75 * 80% = x * 75%
52.60 = x * 75%
70.13 = x
